LAURENS P. DIXON, OE NEW YORK, AND GEORGE E. ]?OST, OF BROOKLYN, NEWYORK, ASSIGNORS TO THE FIRM 0F ANDERSON & PRIGG-E, OF NEW YORK, N. Y.

BINDER-FRAME.

To all whom 'it may concern:

Be it known that we, LAURnNs P. DIXON, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, county andState of New York, and GEORGE E. Fos'r, a citizen of the United States,and a resident of Bay Ridge, borough of Brooklyn, county of Kings, andState of New York, have made and invented certain new and usefulImprovements in Binder-Frames, of which the following is aspecification.

Our invention relates to an improvement in binder frames adapted to beused in connection with loose-leaf ledgers and the like, the object ofthe same being to provide an article of this kind which shall beeconomical to manufacture and assemble, strong, durable and efficient inuse, and the parts so constructed and arranged that the binder plates,moving transversely with relation to the back plate, shall be truly andperfectly guided in their travel, in order to operate easily and freely,means being provided to retain them in perfect alinement.

A further obj ect is to so construct the lugs to which the telescopictubes are secured that they may be easily and readily assembled to thebinder plates and without danger of movement thereon.

A further object of the invention is to improve in various ways upon theconstruction of the frame shown and described in Letters Patent No.968,188, granted to LAU- RENS P. DIXON, on August 28', 1910, and withthese and other ends in view, our invention consists in certain novelfeatures of construction and combinations of parts as will behereinafter fully described and pointed out in the claims.

In the accompanying drawing, Figure 1 is a bottom plan view of a binderframe constructed in accordance with our invention. Fig. 2 is asectional view of the same taken on the line 2 2 of Fig. 1. Fig. 8 is atransverse sectional view taken on the line 3-3 of Fig. 1. Fig. 4t is adetached view in perspective of one of the retaining lugs. Fig. 5 is asimilar view of a guide block, and Fig. 6 is a similar view of one ofthe guide rods.

Referring to the drawings, 10 represents the back of the binder, curvedsomewhat in cross-section, and preferably covered with cloth or fabricto lend thereto a neat and Specification of Letters Patent.

attractive appearance, this back being provided with the downwardlyextending ends 12, through one of which is formed the opening 18 for theentrance of a key to engage with the squared end of the threaded shaft14. This shaft 111, as in similar structures, is provided at one end 15with a right-hand thread, and at its opposite end 16 with a left-handthread, the shaft being journaled near its extreme ends in the guideblocks 17, one of these blocks being clearly shown in perspective inFig. 5. These blocks serve two `aurposes, viz., to not only form abearing for the rotating shaft 111, but also as a guide to nicely directthe movement of the guide rods 18 when traveling with the binder plates19 to which they are attached in a direction toward or away from theback 10. These guide blocks 17 are each provided with grooves orrecesses 20, in which lit andv move one side or iange of the guide rods18, these rods being preferably formed in the shape of an angle iron,the side 21, which fits into the groove 20, being recessed to form ashoulder 22 to strike against the end of the block 17 and thereby limitthe lateral or transverse movement or travel of the rods and binderplates 19 to which they are secured, as hereinafter described. Theblocks 17 are also each recessed in their lower or under side, and' ineach fits the section 23, the lower side of which lies flush with theunder side of the block 17, when the parts are assembled, and its upperside liollowcd out to correspond with the rounded upper side of therecess, the same forming a circular opening 21, in which is fittedor'journaled the end of the threaded rod or shaft 111, the latter beingslightly cut away as illustrated at 25, Fig. 2, where it is fitted intothe block 17, these means preventing any endwise movement of said shaft.The blocks 17 are secured to the back plate 10 by means of the screws orrivets 2G passing through the openings 27 formed in said blocks, andinto the back plate, where, if desired, the ends of said rivets orscrews may be upset. These guide rods 18, or those shown and describedas being in the form of angle irons, may be of any desired shape, butthe shape thereof shown and used in connection with the guide blocks 17,constructed and arranged as described, we believe at the present time tobe the better form of construction, particularly because such avoid thenecessity of the accurate tting of the parts necessary in other forms ofbinder, in order to have the device work freely and smoothly. Theseguide rods are riveted or otherwise secured to the binder plates 19,and, traveling in the grooved or slotted blocks 27, guide or direct saidbinder plates in their lateral or transverse movement with relation tothe back plate, the several parts being held in proper alinement andpreventing any twisting' movement thereof. These binder plates,preferably shaped as illustrated, are provided with the blocks 30,illustrated in perspective in Fig. 4, these blocks being provided on oneside or surface with the lugs or projections 31, and on the under sidewith the lug 32. In each of the binder plates 19 are4 formed openings,through which these lugs 31 pass and upset on their extreme ends againstthe inner side or surface of said binder plates, the said plates beingalso provided with openingsv through which extend the lugs 3Q, thelatter being then bent as illustrated in Fig. 3 to assist in holding theblock in place.

lWe have found in actual practice that by thus forming the block withthe two holding lugs on the one side, and the one lug on the under side,said block is tight-l5T and securely held in position against. movementor accidental disengagement from the binder plate. Into these severalblocks 30 are pinned or otherwise secured the telescopic rods and tubest0-et1, these tubes and rods being used for the same purpose and in thesame manner as in the usual form of binder frames, for instance, likethose shown and described in the patent, supra. Our device is alsoprovided with the traveling nuts 42-113 threaded on the shaft 14, andwith which are connected the inner ends of the levers 44, the outer endsthereof being pivoted to the binder plates 19, as has heretofore beencommonly done in binder frames of this particular type, and whichtherefore need no detail description.

It will be understood that when the shaft 14 is rotated, the nuts 42 and43 will be caused to travel toward or away from each other, the levers4A causing' the binder plates i to travel toward or away from eachother,

and transversely with relation to the back 10, the movement of suchbeing guided by the rods 1S traveling in the grooved stationary blocks17, the rods 40 at the same time traveling within the tubes 41.

lVhat we claim is 1. A binder frame comprising a back; two

blocks formed separate from said back and secured thereto and each ofwhich blocks is provided with two transversely extending open grooves;two binder plates movable toward and from one another and transverse tosaid back; two guiding members secured to each of said binder plates andthe free ends of which slide in the grooves aforesaid; and means formoving said binder plates.

2. A binder frame comprising a back; two blocks formed separately fromsaid back and secured thereto and each of which blocks is provided withtwo transversely extending open grooves located in opposite sidesthereof; two binder plates movable toward and from one another andtransverse to said back; two guiding members right angular incross-section secured to each of said binder plates and the free ends ofwhich slide in the grooves aforesaid and move in contact with the sidesof said blocks; and means for moving said binder plates.

3. A binder frame comprising a back; two blocks formed separate fromsaid back and secured thereto and each of which blocks is provided withtwo transversely extending open grooves and with a bearing in the basethereof; two binder plates movable toward and from one another andtransverse to said back; two guiding members secured to each ofsaidbinder plates and the free ends of which slide in the grooves aforesaid;a shaft having journal portions adapted to lie within the bearingsaforesaid of said blocks and having a right and a left thread formedthereon; a traveling nut upon each of said threaded portions; and linksconnecting each nut with each of said binder frames.

4L. In a binder frame, binder plates movable toward and from oneanother; blocks secured to each of said binder plates and each of whichblocks is provided with a lug upon one face adapted to extend throughsaid binder plate and to be upset upon the inner surface thereof, andwith a second lug upon another face adapted to extend through saidbinder plate and to be bent into contact with the inner surface thereof;and telescoping members, the outer ends of which are secured in saidblocks.

Signed at New York, in the county of New York, and State of New York,this first day of June, 1911.
